Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to an apparatus for serving rice in a bowl in fixed quantities.

``Prior art'' In conventional rice metering machines, the rice in the metering bowl is placed in a bowl while being cut by the upper and lower shutters, so a shutter cut surface is formed on the top surface of the plated rice. Since the food was not arranged in a natural manner, it spoiled the good impression of the customers.

``Problems to be Solved by the Invention'' The present invention automatically erases the shape of the metering bowl and the cut surface of the shutter from the top surface of the plated rice, and automatically arranges the plated rice into a natural plated state. The purpose is to attach.

"Means for Solving the Problems" The present invention provides a rotating device for lowering rice at the lower part of the hopper, and a cylindrical body connected to the lower part of the hopper with a rice quantity container by alternately opening and closing upper and lower shutters,
Directly above the upper shutter, a through hole is bored in the opposite wall of the cylindrical body along a horizontal common center line, and a light emitting tube is installed at the outer end of one of the through holes, and a light receiving tube is installed at the outer end of the other through hole. , the rotary device for lowering the food is stopped, the upper shutter is opened, the lower shutter is closed, and the light is received by the light receiving stop signal of the light receiving tube which is not blocked by the falling food but is blocked by the accumulated food on the upper shutter. The rotating device is driven by a light reception signal from the tube, and the upper shutter is closed and the lower shutter is opened by a light reception stop signal from the deposited rice, and the lower shutter is formed so that the descending deposited rice due to the opening of the lower shutter is not cut by the closing operation of the upper shutter. In the rice quantity serving machine, the distance between the center line and the upper shutter is smaller than the distance between the upper and lower shutters.

"Operation" Therefore, when the rotating device 5 is rotated when the upper shutter 8 is closed, the shutter 8
Half of the amount of rice 19 is deposited on top of the luminous tube 12.
Since the light receiving tube 13 stops receiving the light, the brake motor 14 is stopped in response to the signal, and the rotating device 5 is immediately stopped, so that no more than half of the amount of light is deposited. In this state, the lower shutter 9 is closed by the signal and the upper shutter 8 is opened, so that the half-sized rice 19 is lowered into the metering chamber 7. Therefore, the light receiving tube 13 receives the light from the light emitting tube 12, and the signal rotates the brake motor 14 to rotate the rotating device 5, so that the rice in the hopper 2 is placed on top of the half cooked rice 19 in the box 7. It falls and blocks the light from the arc tube 12 (this state is shown in FIG. 5). And as mentioned above, the light receiving tube 1
In response to the signal No. 3, the rotary device 5 is stopped and the food stops lowering, and at that point the upper shutter 8 begins to close and at the same time the lower shutter 9 is opened, so the food that is above the level of the upper shutter 8 is moved to the upper shutter. Since the shutter 8 descends downward while the shutter 8 is closed, the rice descends without being cut into a flat shape by the shutter 8, and the Masunai rice is stored in the lower bowl 18. . Closed upper shutter 8
When the rotating device 5 is started, half the amount of rice 19 is deposited on top again, and this process is repeated.
That is, before the upper shutter 8 starts to close, the fallen rice is placed on the half-loaded rice on the lower shutter 9, as shown in FIG. The state shown in the figure is reached, and in that state, the light beam is blocked and the upper shutter 8 starts to close, and at the same time, the lower shutter 9 is opened to store the fixed amount of rice in the bowl 18 without cutting the top surface of the rice. The upper surface does not have to be flat, but can have an uneven surface or a spiral surface.

"Example" A hopper 2 is provided inside a heat-retaining machine box 1.
A pair of horizontal rotating shafts 3, 3 are provided at the lower part of the rotary shaft 3, and a comb-like arm 4 is provided on the same rotating shafts 3, 3 to form a rotating device 5 for lowering rice.
form. At the bottom of the hopper 2 is a cylindrical body 6.
are connected to form a rice bowl 7 in the middle of the cylindrical body 6. This box 7 has upper and lower alternate opening/closing shutters 8,
9, through holes 11, 11 are bored in the opposing walls 10, 10 of the cylindrical body 6 directly above the upper shutter 8 along the horizontal common center line a, and the outside of one of the through holes 11 is At one end, connect the arc tube 12 to the other through hole 1.
A light receiving tube 13 is provided at the outer end of the light receiving tube 1, and the brake motor 14 of the rotating shafts 3, 3 is driven and stopped by a light receiving or extinction signal from the light receiving tube 13. The distance between the center line a and the upper shutter 8 is made smaller than the distance between the upper and lower shutters 8 and 9. The rotating shafts 3, 3 are connected by meshing gears 15, 15 and rotate in opposite directions. The light receiving tube 13 is not blocked by the falling rice shown in FIG. 4 because the gap between the grains is large, but is blocked by the accumulated rice. Then, the upper shutter 8 starts to close in response to the light reception stop signal caused by the above-mentioned interruption.
At the same time, the lower shutter 9 is opened, and the upper surface of the piled food that descends due to the opening of the lower shutter 9 is adjusted so that it will not be cut by the closing operation of the upper shutter 8. In the figure, 16 indicates a heat-insulating lid for the hopper 2, and 17 indicates a lever for opening and closing the shutter, which is operated by a cylinder or a cam.The cylinder is operated by a solenoid valve, and the cam is operated by a variable speed motor and by the above-mentioned signal. It works.

"Effects" Since the present invention is configured as described above, when the upper shutter 8 of the metering tank 7 is closed, the upper rotating device 5 is stopped and the rice is stopped descending, and the rice in the upper shutter 8 portion is heavy. Since the rice is not tightened by the shutter 8, no cut-off plane is formed on the metered rice cut off by the shutter 8, and the natural uneven surface is maintained and the rice can be served in a natural state in the bowl 18.
